    Hi Dobby,

    You do not need to use CRC module for CAN communication. CAN Hardware automatically generates and checks the CRC field during transmit and receive.

    The CAN protocol itself defines the CRC field (CRC-15 for classical CAN). The CAN controller automatically calculates CRC and appends it to the frame on transmitter side, and on receiver end CAN controller automatically checks the CRC.

    If CRC is wrong the frame is rejected and an error frame is generated.
